Answer:
The answer to your question is A) x = 1
Step-by-step explanation:
We know that f(x) = 2x + 3 and g(x) = -x + 6
But f(x) = g(x)
Then, 2x + 3 = - x + 6
2x + x = 6 - 3
3x = 3
x = 3/3
x = 1

Answer: 42.21 km
Step-by-step explanation:
We can solve this using trigonometry, since we have the following data:
is the the angle of elevation
is the horizontal distance between the plane and the radar station
is the hypotenuse of the right triangle formed between the radar station and the airplane
Now, the trigonometric function that will be used is <u>cosine</u>:
because
is the adjacent side of the right triangle
